In-the practice of my invention I provide a main frame 10 which is elongated in form' and composed of two parallel channel bars 11, the channels of which are directed in wardly toward each other, and these bars are joined at the top by a cross piece 12 having a forwardly directed eXtension13, and to one side of the cross piece is secured a handle member 14:. A supplemental frame 15 is secured to and between the side bars 11 adjacent to the lower endportion thereof and at a predetermined distance from the lower ends of said bars.

is movably mounted in the supplemental frame 15 and comprises atop cylindrical portion 17 and a reduced bottom portion 18, which passes through the bottomof the supplementalframe 15, while the top cy lindrical portion 17 normally projects beyond the toprof the supplemental frame 15 as shown at 19 anda spiral spring 20is. mounted in the supplemental frame 15 and operates to normally hold themember 16 mm oFrIcE. I

A nail support andguiding member lfi in a raised position. The member 16 is pro vided with; a central bore 21 which opens outwardly through the top and bottom ends of said member, the topportion of said bore being enlarged as shown at 22. .A nail drive ing rod 23 is mounted to move vertically in the bores 21 and 22, and isnormally held ina raised position by a spring 24, as clearly shown in Fig. 6 to normally project the upper end portion 25 of the rod 23 beyond the top of the member 16, figure.v I

The top of the'member 16-.is provided with a plate 26having a fibrous'facing 27, both of which are held in positionby screws 28, while the bottom face of the member 16,

as shown in said or the extension 18 thereof, is providedwith a fibrous facing 29 held in place by screws 30. One side of the member 16 is cut out to form an aperture 31 as clearly shown in Figs. 6 and 8, which is placed in communication with the bore 21 by a passage 32 shown in Fig. 6.

A nail feeding hopper 33 is connected with the top portion of the supplemental frame 15, as clearly shown in Figs. 1 and 6 and is placed in communication with the aperture 31 of the member 16 by a port or passage 34. The member 16 is provided approximately centrally thereof with two forwardly directed ears 35 through which is passed a pin 36 on which is rotatably mounted a nail'delivery device 37 consisting of top and bottom, similarly formed, disks 38 provided in the periphery thereof with a plurality of notches 39 in vertical alinement. The disks 38 are spaced apart by a ratchet wheel 40 to which said disks are secured and as will be seen the disks 38 project into and are adapted to operate in the aperture 31 of the member 16 to control the passage of nails through the aperture 31 into the bottom portion of the bore 21 of the member 16. 7

A main lever 41 is pivoted to a cross piece 42 secured to the bars 11 approximately centrally thereof, as clearly shown in Figs. 2 and 3. The lower end portion of the lever 41 operates in a guidemember 43, connected with and forming part of the supplemental frame 15 and the main frame 10, said lever being cutout as shown at 44 where it operates in said guide member.

The lower end of the lever 41 is bent outwardly, downwardly and inwardly to form a support 45 for a pawl 46 which operates in connection with the ratchet wheel 49, the. pawl 46 being normally held in engagement'with the ratchet wheel by a spring 47 A spring finger 48'is secured to the supplemental frame 15 and operates in connection with the ratchet 40 to hold it against rotation in one direction, all this construc-' tion being clearly shown in Figs. land 80f the drawing.

The upper end portion of'the main lever 41 is cut out as shown at 49 and provided above the cut-out portion 49 with an enlargedcam portion 50, and the upper end of said lever passes through andoperates in an elongated aperture 51 in the extension 13 of the cross piece 12 as clearly shown in Figs. 1 and 2.. V

The mainframe 10 is provided approximately centrally thereofwith a cross mem ber 52 which extends forwardly and aids in supporting a nail receiving casing or hopper 53, and it will be noted that the lever41 passes through and operates in a slot 54 in the cross member 52 of the frame, as clearly shown in Fig. 2.. A bar'55 passes through and operates in the cross member 52, said I hammer bar being provided at its lower end with a hammer head 56 adapted to operate in connection with the member 16 as clearly shown in Figs. 1 and 2. The hammer head is provided on the opposite sides thereof with extensions 57 which operate in the channels of the side bars 11 of the main frame which in combination with the cross bar 52 serves to guide the bar and hammer head 56 in their vertical movement. A spiral spring 58 is mounted on the bar 55 between the'cross member 52 and the hammer head 56 and serves to normally hold the head and bar in a depressed position. r p

A supplemental handle member 59 is secured to the bar 55 above the cross member 52 and by means of which the bar 55 and hammer head 56 may be raised and lowered in the main frame 10, the inner end of the handle member 59 being apertured as shown at 60 to receive the lever 41 whereby in the upward movement of said handle member, the lever 41 will be moved laterally on its pivot by reason of the cam-shaped portion 50 onthe upper end portion of said lever. In the upward movement of the bar 55, the upper end portion thereof, passes through an aperture 61 in the top of the cross piece 12 of the main frame 10. v

The nail receiving casing or hopper 53 is provided approximately centrally thereof with a shaft 62 on which is mounted within. said casing a drum 63, the periphery of which is provided with a plurality of pairs of projecting pins 64 which areadapted to automatically pick up the nails 65 in the casing 53 to feed the same, one by one, into the machine. The bottom of the casing 53 is curved as shown at 66 in Fig. 1 to bring the nails 65 into contact with the periphery of the drum 63 to enable the separate pairs of pins to engage said nails and deliver them through anopening or discharge 67 at one side of the bottom of the casing 53 through which the nails drop into a chute 68 at the bottom of the casing 53 and pass downwardly over a slotted guide and supporting member 69, as clearly shown in Figs. 1, 4, 5 and 7. The free end portion of this memher is provided with an enlarged slot or opening 70 through which the nails 65 are adapted to drop intothe hopper 33.

The dropping of the nails into the hopper 33 is controlled by a nail feeding device 71 supported on an arm 72, secured to one side of the main frame 10, as shown at 73 in Fig. 5, and this feeding device consists of a top disk 74, the periphery of which is provided with a plurality of notches 75, and below said disk is'a supplemental disk 76 havin a plurality of spaced and projecting pins 7. Y

elow the supplemental disk 76 is a ratchet wheelv 78 in connection with which a pawl with said ratchet wheel, as clearly shown in Fig. 5. I w

The guide and supporting member 69 is provided adjacent'to the feeding device 71 with an enlarged portion 84 at one side thereof, in which is mounted atensionally operated pin 85 having an outwardly di rected arm 86 which is adapted to operate in connection with the pins 7 7 of the feeding device 71 to move the tension of the spring 8 Thepin 85 is adapted to operate in connection with the nails 65, or on of said nails supported in a member 69 to normally hold said nail against movement into the feeding device 71 until the pin 85 is releasedby a pin-77.

Pivoted to a cross piece 88 secured to the mainframe 10 is a supplemental lever 89, the lower end of which is pivotedto the lever 411 as shown at 90 and the upper end of which carries a spring operated pawl 91,

which operates in connection-with a ratchet wheel 92 on the inner end of the shaft 62 941 is mounted. in this enlargement and pro 7 jects at oneside thereof, and mounted within the sleeve 9 1- is a spring operatedpin 95,

the outerend of which is provided with a head 96 which operates in connection with the lever 41, which lever normally holds the pin 95 111 1ts extended posltlon whereby V on the inward'movement of the lever 11 the spring 97 on the pin 95 will move said pin inwardly into the aperture 34 to engage a nail therein, or prevent the passage ofmorethan a single nail frolnthe aperture 34 or the cut-out portion 31 downwardly into the bore 21.

From the foregoing the operation of my improved portable nail driving machine will be readily understood when taken in connection with the accompanying drawings and the following statement. The normal position of the various parts ofthe machine is that shown in Figs. 1 and 2, and when it is desired to drive a nail into a fioor'or other surface, the machine is placed upon the floor or other surface lndicated'at 98 in shown in Fig. 6. pin 85 against the"- to saidlever 11' is also moved inwardly'to this operation, thenail d li device 37,

Fig.6 so that the bottom of the frame 10 rests upon the floorand themember 16, or. the extension 18 thereon, ,alsorests upon the floor, after which the handle member f59 is grasped by one hand of the operator and is pulled upwardly, which operation raises the bar 55 and hammer head 56 inthe frame 10 against the tensionof the spring 58. In this operation, the lever 41 or the lower end portion thereof is moved inwardly by the operation of the cut-out portion '60 of the handle member 59 on the cam portion .50 of said lever, the-inward movement of the lowerv end portion of the lever 11 moves the pawl 46 inwardly to rotate the delivery device 37 so as to bring one of the notches I 39 on each of the disks 38 in alinement with *the cut-out portion 31 of the member 16 to permit a nail 65 to dropinto the position In this operation the 8% spring operated pin prevents the drop of the other nails through the delivery device on the inward movement of the lever, 11, as above described, the lever 81 pivoted 9O rotate the nail feeding device 71 to bring one of the notches 75 of thedisk 74: in line with'the enlarged slot or opening-7O of "the'member 69,- as clearly shown in Fig. 5,

to permit one ofthe nails 65 to drop into 95 the hopper 33. In this last named opera tion, it will be apparent, on a consideration of said figure, thatthe pin 85 holds the next adjacent nail 65 against movement. In the inward movement of the lever 11 the supplemental lever 89 is also oscillated on its pivot to rotate the drum'63 in the casing 53 byreason of the engagement of the pawl 91'with the sprocket wheel 9:2 on the shaft 62 of said drum. i

After the handle member59 has been raised to the full extent and the various operations, above described, completed this handle member is moved downwardly by the operator, who exerts sufiicient force on the handle member as to drive the nails 65 partially into the floor or floor surface 98 indicated at '99 in Fig. 6, it being ap parent that the hammer 56 in its down ward movement strikes the projecting end portion 25 of the hammer rod 23, which rod drives the nail, as above described.

The handle member 59 'is again raised in the manner hereinbefore' set out and, in

and the nail feeding device 71 will again be operated to bringthe unnotched portions of theTdisks I38 and 7 1 respectively into line with the cut-out portion3l and enlarged slot 7 0 respectively, to prevent the passage of v other nails through said delivery and feeding devices. Itwill be apparent that in the last named operation of the nail feeding de vice, one of the pins 77 will engage the finger. 86 to release thepin' 85 from one ofthe nails 130 65 held thereby to permit this nail to drop into position to. engage an unnotched portion of the disk 74. It will also be apparent that the drum 68 is operated in the last namedoperation to continue the feeding of the nails 65 onto the member 69 so as to keep a plurality of said nails always in position ready for passage into and through the feeding device.

The handle member 59 is again moved downwardly, as above set out, and in this operation the plunger rod 23 drives the nail 65 fully home as indicated at 100 in Fig. 6, and at the same time countersinks the head of this nail as is shown at 101 at theleft of Fig. 6, where I have shown a nail previously driven into the floor or other surface 98.

From the foregoing, it will be apparent that my improved machine is much the same,

in'general operation as that of the nailing machine shown and described in the patent hereinbefore referred to, except that the various details of construction for accomplishing the desired result are changed to suit the machine as constructed. The chief fea= ture of my present invention is in the provision of 'a comparatively light machine which can be readily carried around. from place to place by the operator and placed in the desired position when a nail is to be driven and to drive said nail without exerting a great amount of effort. It is also ap parent that the machine will be made of suf ficient height to enable the operator to comfortably manipulate the machine when in a standing posture. a

It will also be understood that while I have described the machine as being operated to drive nails by two strokes of the hammer head 56, it will be apparent that I am not necessarily limited to this construction, as the nails may be driven in a single operation, if desired, 7 and various other changes in and modifications of the details of construction herein shown and described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.
